how to create Extension in hybris ?

What is an Extension?

An extension is an encapsulated piece of the Hybris Commerce Suite that can contain business logic, type definitions, a web application, or Hybris Management Console (hmc) configuration.

There are two types of extensions 1. Predefined 2. User defined Extension.

Ex: Cuppy Extension-Predefined

Ex: Student Extension-User Defined created in Custom folder

How to create an Extension?

1. Open the Ant view and invoke the platform's task extgen. This will ask you to

• Select yempty for the extension template

• Enter the name (student) for the extension.

• Enter the package prefix de.hybris.platform.student

2. The Ant script will now create a skeleton extension for you in YOURPATH/bin/custom/student. 

3. Append the new extension to config/localextensions.xml:

config/localextensions.xml:

<extensions>

…….

<extension name=”student”/>

</extensions>

4. Stop the application server.

5. Run ant all

6. Start the application server

7. Import the generated extension into your Eclipse environment

• Right-click in package explorer and select Import

• Select General|Existing Projects into Workspace and browse to the new extension YOURPATH/bin/custom/student Make sure that the Copy projects into workspace check box is not checked before clicking on the Finish button

• You should now see the extension in your Eclipse Package Explorer

8. Open the hybris administration console http://localhost:9001/platform/extensions in a web browser and log in as admin nimda. You will get an overview on the available extensions and, if the extension comes with a core extension module, an hmc extension module, and a webmodule depicted by the webroot and a core + extension module. As you can see, student contains a core module and a web module.

9. Because we do not need a web module for this basic extension, we will disable this in student /extensioninfo.xml

When you perform ant target extgen then an extension will be created in custom folder in the following structure shown below:
